Answer:
Infrasound vs. Ultrasound: Infrasound is sound that is below the lower limit of human hearing, below 20 Hz, and ultrasound is above the upper limit of human hearing, above 20,000 Hz. Individuals use infrasound - this recurrence run for checking seismic tremors and volcanoes, graphing rock and oil developments underneath the earth. Infrasound is described by a capacity to get around hindrances with little scattering.
For instance, a few creatures, for example, whales, elephants and giraffes convey utilizing infrasound over significant distances. Torrential slides, volcanoes, seismic tremors, sea waves, water falls and meteors produce infrasonic waves. Symptomatic ultrasound, additionally called sonography or demonstrative clinical sonography, is an imaging technique that utilizes high-recurrence sound waves to create pictures of structures inside your body. The pictures can give important data to diagnosing and treating an assortment of ailments and conditions.

Infrasound is described by a capacity to get around hindrances with little scattering.

B. irregular
C. barred spiral
D. normal spiral
Answer:D:normal spiral
Explanation:
Answer:
D
Explanation:
3.0 meters, and then returns to first base.
Compared to the total distance traveled by the
player, the magnitude of the player’s total
displacement from the batter’s box is
(1) 3.0 m shorter (3) 3.0 m longer
(2) 6.0 m shorter (4) 6.0 m longer
Distance is a measure of the length of space covered over a certain period of time. While displacement is the change in position of an object from its starting point. Displacement is 6.0 meters shorterthan distance.
Total distance covered :
(Batter's box - > first base) + (beyond first base) + (return to first base)
Total Displacement :
(Batter's box - > first base) + (beyond first base) - (return to first base)
Difference in magnitude of Distance and Displacement :
Therefore, displacement is 6m shorter

Answer:
(2) 6.0 m shorte.
Explanation:
Total distance = Distance from batter’s base to first base + Distance covered in overrunning + Distance covered in returning to first base
Total Distance = 27.4 + 3 + 3 = 33.4 m
Total displacement = Displacement from batter’s base to first base + Displacement covered in overrunning + Displacement covered in to returning first base
The 2nd and 3rd term will have same magnitude but opposite direction so, they will cancel out each other. Hence,
Total Displacement = 27.4 m
Hence, displacement will be 6.0 m shorter than distance.
By definition, we have to:
The environmental impact are the consequences that some of the human activities produce on the environment.
The concept can be extended to the effects of a catastrophic natural phenomenon.
Human activities, such as fuel combustion and deforestation, have intensified the greenhouse effect, causing global warming.
It has been estimated that if emissions of greenhouse gases continue at the current rate, the temperature of the planet could exceed historical values in 2047, with harmful effects on ecosystems, biodiversity and endanger the livelihood of people on the planet.
Answer:
True.
Human activities can have an impact on natural disasters.
Human activities can have an impact on natural disasters is true
The things humans do can affect natural disasters. Natural disasters are events that occur because of nature and its processes. However, human actions can also make these events happen more often, be worse, and affect more people in different ways.
Climate change is happening because of humans. We are releasing greenhouse gases when we burn fossil fuels and when we cut down trees. This is affecting the Earth's climate. This can cause more often and stronger natural disasters like hurricanes, droughts, heatwaves, and heavy rainfall.
Hence, Human activities can have an effect on natural disasters is a true statement.
